Singers Selena Gomez and Justin Bieber no longer feature in Billboard Music's list of powerful couples.

Gomez and Bieber have been going through a rough patch in their relationship and there have been multiple reports of the couple breaking up and getting back together. The couple broke up after Bieber allegedly cheated on Gomez in December last year.

A tweet from the official Twitter account of Billboard on Saturday read: "We had to remove Justin & Selena from our list of top celebrity couples, but we added Chris & Rihanna and Katy & John."

The couples were ranked according to their combined U.S. album sales from 1991-present, according to Nielsen SoundScan.

Billboard has listed Garth Brooks and Trisha Yearwood as the most powerful couple, followed by R&B singer Beyonce Knowles and rapper husband Jay-Z.

Also in the list are singers Rihanna and boyfriend Chris Brown. The pair recently got back together after a dramatic break-up in 2009. Scroll down to see Billboard's most powerful couples in music.
